METALLIC ROOFING.

Specification of Letters Patent.

Patented Feb. 10, 1920.

Application filed November 27, 1918. Serial No. 264,395.

To all 'whom it may concern:

Be it known that I, ARcANonL PERRUSI, a citizen of the Argentine Republic, residing at No. 1767 Mdanos St., Buenos Aires. Argentina, have invented certain new and useful Improvements in Metallic Roofing, of which .the following is a specification.

The present invention refers to a new joint or coupling for metal sheets, corrugated or otherwise and has for its essential object the provision of a special rafter to which are fitted or attached the adjoining edges of the said sheets.

Another object of the present invention is to provide a rafter of the kind specified, which in construction is composed of the said sheets and serves as a girder and permits of the total suppression of the latter.

The invention may be applied without distinction to permanent or provisional constructions, and to roofs, walls, fences, etc., in which flat or corrugated metal sheets are employed. w

The rafter in accordance with the present invention consists essentially of a metal plate bent to the shape of a U, having at the upper part flanges atright angles to its sides, and on the sides projecting ribs parallel to the said flanges.

In order that the invention may be clearly understood and readily employed, it has been represented by way of example, in several of its forms, in the attached drawings, in which:

Fi re 1 is a view from above of two metal sheets joined by the rafter in accordance with the present invention.

Fig. 2 is a section of one of the saidmetal sheets. 4

Fig. 3 is a vertical cross-section of'the intermediary rafter.

Fig. 1 shows an a'ccessary piece which is employed in combination with the said rafter in joining two sheets.

sponding parts.

With reference to these figures, 1 is a 5 is a cross-section of the joint between two metal sheets in accordance with metal sheet having its longitudinal edges turned up as indicated at 2 and having also longitudinal ribs 3. The intermediary piece is formed by a metal plate of appropriate length and weight bent to the shape of a U, l being the base and 5 the sides. On these sides are ribs 6 and at the top of the U are flanges 7 which project outward and are substantially at right angles to the sides of the piece.

This rafter may be employed to join two sheets in several diflerent ways, as for example in the manner indicated in Figs. 1 to 4, by adjusting the sheets in such a manner that the longitudinal edges 2 of the adjoining sheets 1 rest on the side ribs f the rafter, and employing an additional piece 8 bent in the form of a C, asindicated at 9, which slides; along the upper flanges? of the rafter in such a manner as to gr p between the said flanges and the parts 9 0'fthe covering piece, the turned up portio of the edges of the sheets which it is "required to join. In this manner the sheets? may be joined without the use of nails 01:11? screws, absolutely avoiding percolation of water through the joints, and considerably.

facilitating the setting up and taking down of the parts.

Fig. 6 illustrates a means of screws and bolts as shown at 10.

The adjustment of the sheets with respect different form of the i I invention, in which the covering piece 8 is suppressed and the sheets 1 are joined by to the rafters may differ from that shown in the drawings, without thereby departing from the scope of the invention, which is clearly determined in the clauses of the claim which follow this specification.

In all the forms in which the invention may be employed, either in the case of roofs, or in the construction of walls, either permanent or temporary, girders of any kind may be dispensed with, the rafters resting on 'thefwalls or being fixed in the foundations as required in either case. Claim;

j A waterproof metal roofing including, in combination, a rafter formed of sheet metal and bent transversely throughout its length into a U-shaped configuration, flanges continuing at right angles from the upper portions of the sides of the rafters and projectin iii opposite directions, outwardly exflanged retainer having its flat body portending rl'bsprojecting at right angles from tion resting on the flanges and its flan ed the sides of therafter, the ribs being integral edge portions engaged with the curved e ges 10 with the rafter... and possessing a doublepf the plates on the ribs.
